Michael Thorbjornsen of Wellesley may be only 14 years old, but don’t let that fool you. He already has a number of junior tournament wins, including the MGA Boys Junior Amateur a year ago, and has twice been named the U.S. Kids Golf National Player of the Year. And he won the 14-15 age group at the Drive, Chip and Putt Championship — golf’s version of football’s punt, pass and kick — at Augusta National, the Sunday before leading into The Masters.

He might have scored his biggest win to date last Wednesday as he was the medalist in a Mass. Open qualifier at Spring Valley Country Club in Sharon with a 3-under-par 69, defeating a number of professionals and adult amateurs. The victory gives Thorbjornsen a spot in the Mass. Open at Worcester Country Club (June 13-15).

“The greens were in great condition, which allowed me to putt well,” he said yesterday, noting that the round was played in much better weather than his practice round when he was forced from the course after 17 cold, damp holes. “I could trust my line and my stroke.”

Not bad for an eighth-grader at Wellesley Middle School.

Like the rest of the players in the field, being the medalist wasn’t even on his radar when he started his day.

“I was just looking at qualifying,” he said, adding that he simply wanted to shoot par or better.

Starting on the back nine, Thorbjornsen bogeyed his first hole and made the turn at 1-over par with two birdies and three bogeys, but made four birdies on the front side.

Thorbjornsen plays with a plus-1.1 handicap and is aiming high in his first crack against the adults at Worcester.

“My goal is to win as always,” he said. “Looking at the field, I will be happy to be top five.”

He has not played Worcester before but already knows its steeped history, being designed by Donald Ross, a two-time winner of the event.

Getting a taste of the Augusta National experience, when he defeated nine other competitors in the Drive, Chip and Putt contest, is one that he will remember.

“It was awesome, very special to be in a place, a sacred golf mecca, where legends were made,” Thorbjornsen said. “Not many can say they have walked the grounds of Augusta and (be) live on TV.

“We were treated like royalty by the staff at the hotel, by all the members at Augusta and the PGA. We were greeted by golf’s finest and got to hit balls alongside them. They got to even watch us drive, chip and putt.”

He said that he, along with his mother Teresa and three sisters, were able to stick around to watch the pros play a practice round before getting back to school.

After the Mass. Open, Thorbjornsen has a busy summer schedule lined up as he will try to qualify for Drive, Chip and Putt once again. Among the tournaments he will play in are the IMG Academy Junior World Golf Championship in San Diego and the U.S. Kids Golf Teen World Championship at Pinehurst, N.C.
